B-LINE BQL330 – Frequently Asked Questions
1) What wire sizes can I land on a B-Line BQL330 30A breaker?
The BQL330 terminals accept #14 through #8 AWG, copper or aluminum. That covers a 30A branch circuit in either material, so you can land #10 Cu or #8 Al without an adapter lug.
2) Is the BQL330 a three-phase breaker, or can I use it on single phase?
It is a three-pole, 30A device rated 120/240 V. Three poles is what you need for a three-phase load such as a rooftop unit or a three-phase motor on a panel of that voltage class. If you only have a single-phase 240 V load, a two-pole BQL is the right part instead, and a 120 V circuit takes a single-pole.
3) Can I use this breaker on an air conditioner or heat pump circuit?
Yes. The BQL330 is HACR rated, which is the marking required for feeding heating, air conditioning and refrigeration equipment with group motor loads. At 30A three-pole it suits a three-phase condensing unit whose nameplate calls for a 30A maximum overcurrent device.
4) What panels does a B-Line BQL breaker go into?
BQL is a classic replacement breaker type, built to drop into panelboards that were originally equipped with BQL breakers. Check the breaker chart on the inside of your panel door for the BQL designation, or pull the existing breaker and read its catalog number. If your panel lists a different type, a BQL will not seat correctly on the bus.
5) Can I put this 30A three-pole breaker on a 480 V panel?
No. The BQL330 is rated 120/240 V and interrupts 10 kAIC at 120/240 Vac only. A 277/480 V distribution panel needs a breaker rated for that system voltage; installing this one there is a misapplication.
6) Is 10 kAIC enough for my panel?
The BQL330 interrupts 10 kAIC at 120/240 Vac. That is the common rating for residential and light commercial load centers, but on a service with higher available fault current your engineer's short circuit study may call for a series-rated combination or a higher AIC device. Match the breaker's 10 kAIC to the panel's marked withstand before installing.
7) How much room does the BQL330 take up in the panel?
The breaker measures 3 in high, 3 in wide and 5 in deep, and weighs about half a pound. Being three-pole it occupies three adjacent single-pole spaces on the bus, so you need three consecutive open positions, not just three spaces anywhere in the panel.
8) I need to standardize spare breakers across several buildings. What exactly do I order?
Order by model BQL330 for the 30A three-pole version. The number breaks down as BQL type, 3 poles, 30 amps, so sister sizes in the same family follow the same pattern. Keeping BQL stock on the shelf only helps if the panels in each building are BQL panels, so verify the type on each panel's label before setting a standard.
